Discovery of 100 million-year-old regions of DNA shows short cut to crop science advances
(Phys.org)—Scientists have discovered 100 million-year-old regions in the DNA of several plant species which could hold secrets about how specific genes are turned 'on' or 'off'.
Plant organ development breakthrough
Plants grow upward from a tip of undifferentiated tissue called the shoot apical meristem. As the tip extends, stem cells at the center of the meristem divide and increase in numbers. But the cells on the periphery differentiate ...
Could chloroplast breakthrough unlock key to controlling fruit ripening in crops?
Biologists may have unearthed the potential to manipulate the functions of chloroplasts, the parts of plant cells responsible for photosynthesis.
Mystery of nematode pest-resistant soybeans cracked
For 50 years, the world's soybean crop has depended on the use of cyst nematode resistant varieties of beans, but no one knew how these plants fought off the nematode pests. Now, the secrets of resistant soybean plants are ...
Small weed helps unravel complex plant defence system
(Phys.org)—Arabidopsis thaliana, or thale cress as it is commonly known, made history back in 2000 by becoming the first plant to have its entire genetic code read by scientists, contributing to what i ...
Transparent soil allows detailed study of roots
(Phys.org)—A team of researchers from the James Hutton Institute and the University of Abertay Dundee have developed a see-through soil which will enable them to study roots in detail for the first time.
3-D time-lapse imaging captures twisted plant root mechanics for first time (w/ Video)
Using an advanced 3-D time-lapse imaging system, a group of physicists and plant biologists from Cornell University and the Boyce Thompson Institute for Plant Research have discovered how certain plant roots ...
Study proposes new way to save Africa's beleaguered soils
A Washington State University researcher and colleagues make a case in the journal Nature for a new type of agriculture that could restore the beleaguered soils of Africa and help the continent feed itself ...
New gene could lead to better bug-resistant plants
(Phys.org)—The discovery of a new gene could lead to better bug-resistant plants.
Key genetic mechanism in plant hormone signaling may help protect crops from stressors
Scientists at the Salk Institute for Biological Studies have discovered a key genetic switch by which plants control their response to ethylene gas, a natural plant hormone best known for its ability to ripen ...
Plants unpack winter coats when days get shorter
(Phys.org)—Mechanisms that protect plants from freezing are placed in storage during the summer and wisely unpacked when days get shorter.
Gene breakthrough could boost rice yields by 20 percent
Scientists on Wednesday said they had developed a strain of rice that grows well in soils lacking the nutrient phosphorus, a feat that could boost crop yields for some farmers by as much as a fifth.
Differences in the genomes of related plant pathogens
Many crop plants worldwide are attacked by a group of fungi that numbers more than 680 different species. After initial invasion, they first grow stealthily inside living plant cells, but then switch to a highly destructive ...
Scientists peek at the early evolution of sex chromosomes
Two new studies offer insight into sex chromosome evolution by focusing on papaya, a multimillion dollar crop plant with a sexual problem (as far as growers are concerned) and a complicated past. The findings ...
